Hey I'm looking implement OAuth where user will be navigating to Web for authentication and we will receive access_token . How can do this in Compose Multiplatform project for Android, iOS, Desktop and web version ?

Any supportive doc or guide reference will be appreciated ...

I just did this so I can help. I found no cross-platform library so I rolled my own. This guide and this playground helped.

Are there any other services similar to Zitadel, maybe something closer to KMP appeared in the last 2 years ?

I did that in my Taskfolio project https://github.com/opatry/taskfolio

The Android implementation uses native OAuth with Google API.
On Desktop impl, it redirects to Web browser and listen for Callback URL spawning a short lived web server on localhost.

The oauth code are processed that way.
